1. , a kind of credit sign accidental streakline generating method is characterized in that:

  • Step 111 is prepared a e-file of waiting to sign document in computer system;

    Step 112, the electronic image of the stand-by credit sign pattern of preparation in computer system;

    Step 120 is a data source with the described electronic file content of preparing in the step 111 of waiting to sign document, and the input hash function calculates hashed value;

    Step 130 is used this hashed value of asymmetric-key encryption;

    Step 140 obtains the digital signature value of described e-file;

    Step 160 the described digital signature numerical value that obtains in the step 140, is scattered in the digital pattern of digital signature according to the geometric arrangements of the described stand-by credit sign pattern in the step 112;

    Step 170, the digital pattern of the described digital signature that obtains in the step 160 is laminated on above the electronic image (171,173) of the described stand-by credit sign pattern of preparing in the step 112, make stroke in the digital pattern of described digital signature scratch the videotext of described credit sign pattern, the stroke track of its lap (172,174) forms the digital signature accidental streakline of credit sign pattern, and this streakline constitutes digital signature accidental streakline credit sign with the described stand-by credit sign pattern of preparing in the step 112.
